Hello Appian practitioners,
Following the notes from this discussion,
I tried creating a WEB-API to load a locally available WSDL within the 'Call Web Service' smart service.
My web-api returns the following httpResponse
a!httpResponse( /* * Set an HTTP header that tells the client that the body of the response * will be a CSV attachment. */ headers: { a!httpHeader( name: "Content-Disposition", value: "attachment; filename=" & char(34) & local!username & ".xml" & char(34) ) }, /* * Create a CSV value of 'local!user' and place it in the response body. */ body: rule!TS_test_ProfileXML() /* XML Contents */ )
However, the call web-service is still not able to detect the WSDL.
Appreciate all your help!

I never did this, as it might become a problem over time in case the password needs to be changed.
Did you try to set the content type header to "text/xml" and remove the Content-Disposition header?
Yes, I did try adding the content-type and removing content-disposition, but without success.
Would you recommend any other way of consuming the local wsdl file?
Did you test your API using Postman or SoapUI?
AFAIK there is no simple way to use a local WSDL.
The original WSDL is hosted on an internal server connected via VPN.
All I want to do is to change the soap address location to the latest server and call the new SOAP WSDL.
Any idea if I can do that using Appian's WEB-API? Or shall I host the XML on a different server?
Hi Stefan,
I have seen your older discussion here where you've recommended using Web-api. If possible, can you share a sample code with me?
By any chance, the error message you got is already more specific as it complains about the WSDL version. Could it be that the WSDL is somehow malformed?
The same WSDL is also hosted at a local server which Appian can read. But not the one that I updated and hosted on Appian (web-API)
I am only updating an HTTP URL within the WSDL.
Appian logs suggest the following
I also tried copying the entire XML from a public WSDL 'https://www.dataaccess.com/webservicesserver/NumberConversion.wso' but still the same issue
Did a quick test with the XML of the WSDL from your example copied to a text constant. This works without any issues. Could it be that the security settings for the API are not correct?
I am using the system admin account but it still fails.
First of all, thank you so much for testing it at your end.
And if possible, could you please validate if the content of your cons!TST_WSDL is the same as attached?

Thank you!I see all the values are identical. Looks like it's working in your community environment. Let me try to reproduce it in mine and raise a ticket with Appian.
It might be as simple as URL whitelisting or proxy.
Thank you for your time & help.
